Chart Highlights: Same #1, Tulisa Makes History

Swedish House Mafia locks in a fifth week at #1 with "Don't You Worry Child (feat. John Martin)". The song also currently ranks as the #1 song of 2013, due to this being the first chart week of January 2013.

Calvin Harris remains #2 with "Sweet Nothing (feat. Florence Welch)" for a fifth frame. The single is still growing strong, as it is just 8% lower in overall airplay that the current #1.

"Diamonds (Shahaf Moran Remix)" sits at #3 during its 14th week. Spending 14 frames in the Top 5, it is just 6 weeks under the record set by Rihanna's own "Where Have You Been" (20 weeks).

Christina Aguilera rises 5-4 with "Let There Be Love". The single follows her chart topping hit "Your Body" which spent 2 weeks at #1 in September/October.

Although down 4-5 "Right Now (feat. David Guetta)" is up 9% in airplay, and was barely edged out by Christina's "Let There Be Love". The song is likely to return upwards within the coming weeks.

Vita Chambers rises 8-6 with "Fix You". The single is down less than 1% in airplay, but still manages a somewhat major move.

Macklemore & Ryan Lewis bound 9-7 with "Thrift Shop (feat. Wanz)" courtesy of a 18% gain in airplay.

After one week of absence Tulisa re-enters at #8 with "Young (Gregor Salto Remix)" after peaking at #9 during its original 9 week run. This movement marks the highest re-entry of any song on the CDS Music Chart in all time history.

"Locked Out Of Heaven" dips 6-9 due to an array of new singles charting, and airplay being down 14%.

Ivi Adamou rounds it out as "La La Love" spikes 12-10 to reach the Top 10. It becomes the second Eurovision song to do so after Loreen's "Euphoria" debuted and held at #1 for 3 weeks.

Ke$ha returns to the edge of the Top 10 as she rebounds 14-11 with second single "C'mon". The single is 2 position short of its previous peak and 3 from a new peak.
